Hi Marty,
You should be able to just encrypt your content and add as email Body and you are set. To encrypt, you need the recipient's public key and a set of keyrings for yourself also (public and private). You will need to import their public key into your public keyring and then use it to encrypt the message (or attachment) and then send it to them. You can use the steps below as a template. You will have to fill in the paths for files and enter correct email addresses of course. For more information please see http://users.ece.cmu.edu/~adrian/630-f04/PGP-intro.html

I have tested this code and it works with PGP, so good luck.
